Abstract
Describes a computational environment based on cellular automata and genetic algorithm principles. This kind of approach is useful in a large set of applications, particularly in biological models, including those related to theoretical ecology. The program runs on an IBM compatible personal computer with a visual genetic algorithm display. It would be preferable to have at least a 80386‐based machine to take advantage of its speed of processing. It is menu‐based oriented to facilitate its use by non‐experts, and permits the interference by the researcher in many environmental and behavioural parameters, allowing many kind of studies. Illustrates the program′s capabilities by applying it to a set of simulations in order to demonstrate their effect on the evolution of the biological population.

Abstract
Purpose
The secondary phase decreased the corrosion resistance because of the segregation of Cr and Mo. Therefore, this paper aims to study the precipitation condition and the effect of secondary phase with volume fraction on corrosion behavior.
Design/methodology/approach
Secondary phase precipitated approximately from 375°C to 975°C because of saturated Cr and Mo at grain boundary by growth of austenite. Therefore, heat treatment from 800°C to 1,300°C was applied to start the precipitation of the secondary phase.
Findings
The secondary phase is precipitated at 1,020°C because of segregation by heterogeneous austenite. The growth of austenite at 1,000°C needs the time to saturate the Cr and Mo at grain boundary. When the volume fraction of austenite is 56 per cent (14 min at 1,000°C), the secondary phase is precipitated with grain boundary of austenite. The secondary phase increased the current density (corrosion rate) and decreased the passivation. That is checked to the critical pitting temperature (CPT) curves. The 1 per cent volume fraction of secondary phase decreased CPT to 60°C from 71°C.
Research limitations/implications
The precipitation of secondary phase not wants anyone. Casted super-duplex stainless steel (SDSS) of big size precipitates the secondary phase. This study worked the precipitation condition and the suppression conditions of secondary phase.
Social implications
Manufacturers need precipitation condition to make high-performance SDSS.
Originality/value
The corrosion resistance of SDSS is hard the optimization because SDSS is dual-phase stainless steel. The precipitation of the secondary phase must be controlled to optimize of the corrosion resistance of SDSS. Anyone not studied the precipitation condition of secondary phase and the effect of secondary phase with volume fraction on corrosion behavior of SDSS.

Abstract
Purpose
In this study, super duplex stainless steel (SDSS) was heat-treated. The purpose of this study is to assess the effect of the cooling rate after heat treatment on the pitting corrosion of SDSS.
Design/methodology/approach
The heat treatment from 1,000°C to 1,300°C was applied to SDSS to check the effect of the cooling rate.
Findings
The heat treatment temperature produced a different SDSS microstructure, and the cooling rate led to the growth of austenite. The casted SDSS indicated the presence of heterogeneous austenite, and the precipitation secondary phase under 1.6 per cent precipitated to bare metal. By applying heat treatment and cooling SDSS, its corrosion resistance changes because of the change in the chemical composition. The cooling rate at 5,600 J/s has the highest critical pitting temperature (CPT) at 1,100°C, and the cooling rate at 1.6 J/s has the highest CPT at 1,200°C. Low cooling rate (0.4 J/s) made the secondary phase at all temperature range.
Research limitations/implications
The effect of secondary phase not consider because that is well known to decreasing corrosion resistance.
Practical implications
Solution annealing is taken into account to optimize the corrosion resistance. But that is not consider the cooling rate at each temperature. This study assessed the effect of the cooling rate at each temperature point.
Social implications
Manufacturers need to know the effect of the cooling rate to optimize the corrosion resistance, and this study can be applied in the industrial scene.
Originality/value
SDSS is hard the optimization because SDSS is a dual-phase stainless steel. Corrosion resistance can be optimized by controlling heat treatment temperature and the cooling rate. Anyone not studied the effect of the cooling rate at each temperature. The effect of the cooling rate should be considered to optimize the corrosion resistance.

Abstract
Purpose
Provisions for the minimisation of human error are essential through governance structures such as recruitment, human resource allocation and education/training. As predictors of safety attitudes/behaviours, employees’ personality traits (e.g. conscientiousness, sensation-seeking, agreeableness, etc.) have been examined in relation to human error and safety education.
Design/methodology/approach
This review aimed to explore research activity on the safety attitudes of healthcare staff and their relationship with the different types of personalities, compared to other complex and highly regulated industries. A scoping review was conducted on five electronic databases on all industrial/work areas from 2001 to July 2023. A total of 60 studies were included in this review.
Findings
Studies were categorised as driving/traffic and industrial to draw useful comparisons between healthcare. Certain employees’ personality traits were matched to positive and negative relationships with safety attitudes/behaviours. Results are proposed to be used as a baseline when conducting further relevant research in healthcare.
Research limitations/implications
Only two studies were identified in the healthcare sector.
Originality/value
The necessity for additional research in healthcare and for comparisons to other complex and highly regulated industries has been established. Safety will be enhanced through healthcare governance through personality-based recruitment, human resource allocation and education/training.

Abstract
Purpose
This study aims to develop a conceptual model to understand how customer knowledge management (CKM) affects fitness club membership renewal through the mediation of relationship quality.
Design/methodology/approach
Data were collected outside of fitness clubs using a systematic sampling method. A total of 224 valid responses were collected. Structural equation modelling was used to evaluate the relationship between the constructs of the research model.
Findings
The results indicate that both knowledge from customers and knowledge for customers have a positive influence on customer satisfaction and customer trust. Among them, knowledge for customers has a stronger influence on customer satisfaction while knowledge from customers has a greater influence on customer trust. Additionally, three dimensions of relationship quality (customer satisfaction, customer trust and customer commitment) positively influence membership renewal intention with customer commitment exhibiting the greatest influence on it.
Originality/value
This study combines the theories of CKM and relationship quality management to explain why members will renew their service contracts. By using fitness clubs as an example, this research extends the authors' understanding of how knowledge from and for customers can influence customers' attitudes and behavioural intentions towards service companies.

The purpose of this paper is to examine the effect of internal pores on the tensile properties of a Co–Cr–Mo alloy fabricated by selective laser melting (SLM).
Abstract
Purpose
The purpose of this paper is to examine the effect of internal pores on the tensile properties of a Co–Cr–Mo alloy fabricated by selective laser melting (SLM).
Design/methodology/approach
The size and volume fraction of pores were controlled through high temperature annealing (HTA) and hot isostatic pressing (HIP).
Findings
After HTA, the size and fraction of pores decreased compared with the as-built SLM sample, and no pores were observed after HIP. Tensile tests of the HTA and HIP samples showed nearly similar tensile deformation behavior. From the results, the authors found that the size of the internal pores formed in the SLM process had little effect on the tensile properties. The as-built SLM sample had less elongation than the HTA and HIP samples, which would not the effect of porosity, but rather the effect of the residual stress and the retained ε phase after the SLM process.
Originality/value
Although pores are a main factor that influence the mechanical properties, the effect of pores on the tensile properties of Co–Cr–Mo alloys fabricated by SLM has not been studied. Therefore, in this study, the effect of pores on the tensile properties of a Co–Cr–Mo alloy fabricated by SLM was studied.

Abstract
Purpose
This study aims to investigate the perception of smart tourism technologies (STTs) in creating museum tourism experiences and assess visitors’ intentions to test the impact, the extent and role that STTs play in museum service.
Design/methodology/approach
The investigation was conducted through an online and on-site survey; data were collected in four different museums with 365 museum tourists in four countries. SmartPLS (version 3.3.3) was used to access the measurement and structural model based on path modelling and bootstrapping.
Findings
STTs have a positive impact on creating a memorable tourism experience for museum visitors and are beneficial to revisit intention and positive recommendations. The impact is stronger than traditional services such as museum setting and staff service. STTs can be considered an independent new service to museums rather than complementing existing services. STTs negatively affect tourism’s experience at the communication stage.
Originality/value
Previous studies have noted the growing attention to the museum visitor experience, but the combined impact of new elements, such as STTs, remains an unexplored area. This study addressed the research gap through an empirical investigation and offers guidelines to test museum visitors’ acceptance and fitness for the services provided by STTs. In addition, this study presents a new point of view on the roles that STTs take in museum service, which can be useful for further investigations.
目的
本研究旨在调查智慧旅游技术 (STT) 在创造博物馆旅游体验和评估游客意图方面的感知。测试智能旅游技术在博物馆服务中的影响、程度和作用。
研究方法
研究调查是通过在线和现场问卷调查进行的; 数据是在四个国家的四个不同博物馆中收集的, 共收集了 365 名博物馆游客的数据。 SmartPLS(版本 3.3.3)用于访问基于路径建模和引导的测量模型和结构模型。
研究结果
智慧旅游技术对为博物馆参观者创造难忘的旅游体验具有积极影响, 并有利于重访意向和积极推荐。这种影响比博物馆的环境设置和员工服务等传统服务更强。智慧旅游技术可以被视为对博物馆的一项独立的新服务, 而不是对现有服务的补充。智慧旅游技术对博物馆游客在传播阶段的体验产生负面影响。
原创性/价值
以前的研究已经注意到学界对博物馆参观体验的关注日益增加, 但 STT 等新元素的综合影响仍然是一个未探索的领域。 本研究通过实证调查补充了研究缺口, 并提供了测试博物馆参观者对 STT 提供的服务的接受度和适应性的指南。此外, 本研究提出了 STT 在博物馆服务中的作用的新观点, 这对进一步的研究很有帮助。
Resumen
Propósito
El objetivo de este estudio es investigar la percepción de las Tecnologías Turísticas Inteligentes (TTIs) en la creación de experiencias turísticas en los museos y evaluar las intenciones de los visitantes para probar el impacto, el alcance y el papel que desempeñan las TTIs en el servicio de los museos.
Diseño/metodología/enfoque
La investigación se llevó a cabo a través de una encuesta online y presencial; los datos se recogieron de 365 turistas en cuatro museos diferentes de cuatro países. Se utilizó SmartPLS (versión 3.3.3) para evaluar el modelo de medida y el modelo estructural basado en la modelización de trayectorias y el bootstrapping.
Resultados
Las TTIs tienen un impacto positivo en la creación de una experiencia turística memorable para los visitantes de los museos y son beneficiosas para la intención de volver a visitarlos y las recomendaciones positivas. El impacto es mayor que el de los servicios tradicionales, como la ambientación del museo y el servicio del personal. Las TTIs pueden considerarse un nuevo servicio independiente para los museos, más que un complemento de los servicios existentes. Las TTIs afectan negativamente a la experiencia del turismo en la fase de comunicación.
Originalidad/valor
En estudios previos se ha observado la creciente atención que se presta a la experiencia de los visitantes de los museos, pero el impacto combinado de nuevos elementos, como las TTIs, sigue siendo un área inexplorada. Este estudio aborda esta laguna de la investigación mediante una investigación empírica y ofrece directrices para comprobar la aceptación y la adecuación de los visitantes de los museos a los servicios prestados por las TTIs. Además, este estudio presenta un nuevo punto de vista sobre las funciones que asumen las TTIs en el servicio de los museos, que puede ser útil para futuras investigaciones.

Abstract
Purpose
This research aims to explore the mechanisms by which green marketing practices (GMP) influence customer loyalty (CL) and how green self-identity (GSI) moderates the relationship between green corporate image (GCI) and customer loyalty in the new energy vehicle (NEV) market.
Design/methodology/approach
The study surveyed individuals who had purchased new energy vehicle products through an online platform, resulting in 321 valid questionnaires obtained through a non-probability sampling method. The data were analyzed using the PLS-SEM method to test the proposed hypotheses.
Findings
The research found that green advertisement, green product quality, green product price, external green supply chain management and the salesperson’s green expertise are GMP by the company, and they had positive effects on GCI. Furthermore, GCI had a positive mediating effect between GMP and CL, while green self-identity served as a positive moderator between GMP and CL.
Originality/value
This paper addresses the research gap in the literature on green image and consumer markets, providing a deeper understanding of the mechanisms underpinning GMP and consumer behaviors. These insights can assist companies in shaping a GCI and enhancing CL in the NEV market.

Abstract
Purpose
The purpose of this chapter is to evaluate and discuss the factors that underpin tourists' perceptions of anti-COVID-19 practices in tourist accommodations and destinations, as well as in tourists' experience, satisfaction and behaviour, in order to make recommendations for managers at hotels and tourist destinations.
Design/Methodology/Approach
A survey at tourist accommodations in the Canary Islands was conducted to collect data, and 431 questionnaires were part of the final analysis. The data were analysed with the SPSS27 statistical processing software. Various multivariate techniques such as correlation analysis and factor analysis were used to analyse the data.
Findings
The results reveal that anti-COVID-19 practices at the accommodation are the most important for tourists to feel safe in their visit to the destination. The most important factors in the tourists' experience during the pandemic are those related to communication and behaviour. Satisfaction after COVID-19 is perceived higher if places or items for cleaning and disinfestation are provided to tourists and rooms are naturally ventilated, while intentions to visit after COVID-19 are highest to visit local destinations.
Practical Implications
The results of the research will support scholars and practitioners to recognise the importance of factors that influence anti-COVID-19 practices, tourists' experience, satisfaction and behaviour during the pandemic. In addition, the research offers policy recommendations for maximum benefits for the tourism industry in the Canary Islands and others tourist destinations.
Originality/Value
The chapter was an original primary and exploratory study that surveyed tourists to determine their perceptions of anti-COVID-19 practices, experience, satisfaction and behaviour during the pandemic. The results reveal the most important factors in the construction of the analysed variables, and may be used as a starting point for further hospitality marketing research.

Abstract
Purpose
The purpose of this study is to provide useful data for setting up eco-friendly restaurant (EFR) marketing strategies by analyzing experiential value and well-being perception, lovemarks and behavior intention, before presenting practical proposals.
Design/methodology/approach
The data used in this study were based on a sample of 300 customers at “Seasonal Dining Table” in South Korea. Data were analyzed using confirmatory factor analysis and structural equation modeling.
Findings
As a result of the study, playfulness showed the greatest influence on well-being perception, followed by service excellent, aesthetics and efficiency. In addition, well-being perception was found to have a positive effect on brand love and brand respect. Finally, the role of experiential value, well-being perception and lovemarks as the determinants factors to increase the customer's behavioral intention toward EFR was confirmed.
Practical implications
The present research informed that effectively dealing with four constituents of experiential value (efficiency, service excellence, aesthetic and playfulness) are of utmost importance in building customers' well-being perception. In addition, customers' well-being perception and lovemarks should be improved to boost the level of behavior intention for EFR.
Originality/value
This is the first study to examine experiential value, well-being perception, lovemarks and behavior intention in the context of restaurants. In particular, it is differentiated from previous foodservice studies by examining the relationship between experiential value and well-being perception.
